Phoebe Heyerdahl is a character who has yet to appear in Powerpuff Girls Doujinshi. She is only featured in character art.
Phoebe was born in Kentucky and, at some point, moved to Hillwood at a young age. Her distinctive features include a huge lump of black hair at the top of her head bounded by a small yellow scrunchie, and stereotypes for smart children in animated shows, such as big eyeglasses, a short stature, and squeaky voice. She always tries to be the first one with the answer, and isn't exactly thrilled when someone else does better.
